For those of us outside of Britain (i.e. 98% of us?) the message here isn't "mission accomplished" -- it's "Yes it's possible"

Well, in the sense that it's possible to be eating zero calories in the time between meals. You still need the meals. If you're just looking at brief snapshots, it doesn't tell you much.
It was a widely considered impossible to have more than single digit percentage of renewables even for instantaneous figures. That "limit" has been raised again and again as the world gets more experience with it.
It's great that we've made so much progress that people can say "it's just 90% renewable for 30 mins" but that's a result of decades of hard work.
You are conflating ideas here and it's getting muddled up. Literally nobody ever said that we couldn't handle 100% renewables for brief periods. The single digit percentage you're referring to is not about the renewables, it's about when the renewables aren't there. Its about maintaining grid stability when you don't have dispatchable sources to do it with. Essentially what we've built is a system where the renewables provide a tertiary function- providing power when they want to, but not in a reliable way, so we still have the same carbon based dispatchable resources.
This is not a serious system. We've done a bit of work on th cheap, easy part. Installing some solar panels is easy and costs almost nothing. The storage and transmission of power is 90% of the actual work!
